PROBLEM TO BE SOLVED: To provide a massage machine which attains a three-dimensional stretch or wists by utilizing inflating/deflating bags to be inflated and deflated by an air supply/discharge device.SOLUTION: A pair of left and right inflating/deflating bags 2a to be inflated and deflated by the air supply/discharge device 3a are respectively provided at the seat part 11a and backrest part 12a of a chair body 10a, and a plurality of pairs of left and right inflating/deflating bags 2a and 2a of the backrest part 12a are arranged side by side in the vertical direction. In the state of raising the backrest part 12a, only one side of the pair of left and right inflating/deflating bags 2a and 2a of the seat part 11a is inflated and only the inflating/deflating bag 2a on the same left or right side as the inflating/deflating bag 2a inflated in the seat part 11a of the pair of left and right inflating/deflating bags 2a and 2a at the bottom in the backrest part 12a is inflated simultaneously. Among the plurality of pairs of left and right inflating/deflating bags 2a and 2a arranged side by side in the backrest part 12a, at least only one set of the inflating/deflating bags 2a and 2a in diagonal relationship are inflated.COPYRIGHT: (C)2009,JPO&INPIT【課題】空気給排装置により膨縮する膨縮袋を活用して三次元的なストレッチやひねりを可能にしたマッサージ機を提供する。【解決手段】空気給排装置3aにより膨縮する膨縮袋2aを椅子本体10aの座部11a及び背凭れ部12aに左右一対としてそれぞれ設けると共に、背凭れ部12aの左右一対からなる膨縮袋2a・2aを上下方向に複数並設し、背凭れ部12aの起立状態において座部11aの左右一対からなる膨縮袋2a・2aのうち片側のみを膨張させると同時に、背凭れ部12aにおける最下の左右一対からなる膨縮袋2a・2aのうち座部11aで膨張させた膨縮袋2aと左右同側の膨縮袋2aのみを膨張させ、且つ背凭れ部12aにおいて複数並設した左右一対からなる膨縮袋2a・2aのうち、少なくとも一組の対角関係にある膨縮袋2a・2aのみが膨張するよう構成したものである。【選択図】 図3
